Perfect game (baseball)

From Conservapedia

A perfect game is a game in which a pitcher (or combination of pitchers) throws a full nine-inning game without allowing a single opposing batter on base. This differs from a no-hitter, in that the pitcher(s) may not allow any walks or hit batsmen. By definition, a perfect game will also be a shutout, meaning a game where the opposing team scores no runs.

There have been just 20 perfect games in Major League Baseball history [1] and only one of those occurred in the postseason. The first perfect game was thrown on June 12, 1880, by Lee Richmond of the Worcester Ruby Legs in a 1-0 defeat of the Cleveland Blues.[2] The most recent such game was thrown by Roy Halladay of the Philadelphia Phillies, who blanked the Florida Marlins on May 29, 2010.
